Miller Smith 210 Series Silverline Analytical Regulator, 0-150 PSI, 1/4 FNPT

Reliable High Purity Gas Regulation

When your work demands cleaner gas delivery than a standard welding regulator can provide, the Miller Smith 213-00-00 Silverline High Purity Regulator is the professional's choice. Designed for analytical and laboratory environments, this single-stage regulator ensures that your gas stream remains uncontaminated by the regulator itself. The secret lies in its stainless steel diaphragm. Standard rubber diaphragms can absorb gases and moisture, releasing them later and contaminating your process. The stainless steel diaphragm in the Silverline series creates a hermetic seal that resists inboard diffusion, ensuring that the gas entering your instruments is as pure as the gas leaving the cylinder.

Durability is a hallmark of the Miller Smith brand, and the 213-00-00 is no exception. The entire body, bonnet, and gauge casings are plated, providing a tough, protective shell over the brass bar stock construction. This makes the regulator resistant to scratches, corrosion, and the wear-and-tear of daily industrial use. It is specifically designed for non-corrosive, high-purity gases used in applications like automotive emission analysis, biological research, and precise chemical processing. The regulator is rated for a maximum inlet pressure of 3500 PSI and provides a controllable delivery pressure range of 0-150 PSI, making it versatile for a wide variety of pneumatic and analytical needs.

One of the standout features of this model is its connection flexibility. Instead of a fixed cylinder connection, it features 1/4" FNPT inlet and outlet ports. This allows you to customize the setup for your specific facility—whether you need to mount it on a panel, install it in a gas manifold system, or attach specific CGA fittings for unique gas cylinders. The body is even tapped specifically for rear panel mounting, simplifying installation in test benches or cabinetry.

Operators will appreciate the large, 2-1/2 inch gauges that make monitoring pressure levels effortless, reducing the risk of reading errors. Additionally, the filtered seat design prevents debris from damaging the internal seating surface, ensuring a long, leak-free service life. Backed by the Miller True Blue warranty, this regulator offers peace of mind and precision performance for anyone working with high-purity specialty gases.
